The reality is that for NTSC there is no standard. There is an NTSC variant of WSS discussed in the WSS specification, as well as a way of representing the info in EIA-608. As far as I have been able to gather though, neither have actually ever been used in production. If someone wants to offer some evidence to the contrary, I would be happy to add the support to tvtime and test it with some of my tuner boards (and fix any bugs that in the driver I find). > - Replace the PCM device node with a proper ALSA device. For what it's worth, this has actually been done for the cx18 (but not for ivtv). I just need to do the final PULL request to get it into the mainline v4l-dvb. Cheers, Devin -- Devin J.
